An indirect measurement of the speed of molecules is made with a?

An indirect measurement of the speed of molecules can be made using techniques such as Doppler spectroscopy or light scattering. These methods analyze the behavior of light as it interacts with the molecules to determine their speed indirectly. By studying the changes in the properties of the light, scientists can infer the motion and speed of the molecules.

What is the uncertainty in the measurement for the speed of light?

The uncertainty in the measurement of the speed of light is typically around ±0.3 meters per second. This uncertainty arises from various factors such as experimental errors, instrumental limitations, and environmental conditions. Multiple measurements and techniques are used to reduce this uncertainty and obtain a more accurate value for the speed of light.
